Important: SCR Bus Supplies are designed to be field maintained only. Normal maintenance components (fan, fuses, fuse monitor
switch, printed circuit boards (precharge, gate, and snubber), and precharge relay are available. Additional catalog numbers are
provided for troubleshooting and technical support information only.
(2)
Extensive disassembly is required to replace the fan assembly. Please consider using Rockwell Automation Remanufacturing Services.
(3)
When replacing these fuses, always properly position them so that their fuse trip indicators (plungers) point toward the fuse trip
detection board.
(4)
This is an ESD sensitive component.
(5)
Not required for 1000A Standalone unit, but required for 1000A Master unit or 1000A Slave unit (both mounted in lower location).
(6)
Not required for 1000A Slave unit, but required for 1000A Standalone unit (mounted in lower location) or 1000A Master unit (mounted in
upper location).
(7)
Not required for a 1000A Standalone unit, but required to connect an existing 1000A Master or Slave unit to another 1000A Slave unit
(gate driver circuit board mounted in lower location).
